医院是病人高度集中的场所,病人排泄物和分泌物等内的病原微生物在空气中形成气溶胶或粘染在各种物体上,如果医院环境卫生不良,加上病人抵抗力下降,容易造成医院内感染。为给减少医院内感染提供依据,我们对省级医院空气进行了调查。调查结果如下:1 方法 采用平板暴露法进行采样,每个病房和治疗室的四角和中央在距地面1m高度处放一个普通营养琼脂培养基平板,在空气中暴露5min,立即盖上,放在37℃温箱培养24h,
Hospital is a highly concentrated place for patients, the patient’s secretions and secretions within the pathogenic microorganisms in the air to form aerosol or stick to a variety of objects, if the hospital sanitation, coupled with the patient’s resistance decreased, likely to cause the hospital Infection. To provide a basis for reducing hospital infections, we conducted an investigation of the provincial hospital air. The results of the investigation are as follows: 1 Methods The plate exposure method was used for sampling. At each corner and center of the ward and treatment room, an ordinary nutrition agar plate was placed at a height of 1 m above the ground and exposed to air for 5 min. 37 ℃ incubator 24h,
